在实际工程中泵与风机大量使用，但是其选型和管路设计中往往忽视了系统效应的影响，从而造成了泵与风机的选型不当导致不能正常工作。介绍了系统效应的种类和影响，以及在管网阻力计算中由系统效应引起的附加阻力的计算。并由此得出系统效应对泵与风机和管路的影响。

A lot of pumps and fans are used in tunnel construction. Due to the ignoring of the systematic effect of the pumps and fans during type selection and pipeline design, unfortunately, some of the pumps and fans can not do a good job. The types and influence of systematic effect and the calculation of the additional resistance induced by the systematic effect in the resistance calculation of pipeline networks are presented in the paper. It is concluded that the systematic effect has great influence on pumps, fans and pipelines.
